### 5/5 — 都给我下这个数独

*2026-08-26*

没有广告 界面干净 不会的步骤有提示还有讲解记小数笔记不用来回切换了 非常好的一款软件

### 5/5 — 非常好的游戏

*2026-08-26*

免费 简洁 无弹窗 分等级 分模式，还有数独技巧，非常好！！

### 3/5 — 建议界面优化一下

*2026-08-23*

建议优化九宫格边框线条加粗一点，玩杀手的时候和虚线一样细，很难看清宫位非常影响解题。

**Developer response:** 感谢反馈，您是在深色模式下感觉不容易分辨吗？普通主题下区别已经很大很大了，这里再加粗会影响整体视觉效果的。详细的建议您可以通过游戏内的反馈或发送邮件到shizheqing123@gmail.com来讨论。

### 5/5 — 有了收费好多啦

*2026-08-15*

我曾经玩过，现在有了收费好多了。一般的技法你都放上去了。技法也和人一样也会向前发展的。现在就有两个大拿在做这样的事。

### 5/5 — 好好好👍

*2026-08-11*

很好的游戏，简约设计很中意！对我来熟悉最好不过了

### 4/5 — 解题实时报错开关添加

*2026-08-07*

这个应该添加一个开关，不开的时候直到答完所有格子再显示答案，有时候不知道错在哪里就显示报错，关掉之后复盘更有针对性

**Developer response:** 您好，感谢反馈(^🙏^) 
设置里有这个开关，您可以在设置中打开自由模式即可。

### 5/5 — 非常好的数独游戏，推荐！

### 5/5 — Sudoku Clean

*2026-07-23*

Great app. Nice colors and text sizes can be modified. I can't find landscape mode anywhere, that I my only criticism.
